Steel Cable-stayed Bridge Structure Analysis And Monitoring Method

Starting with the general situation of normal and special-shaped cable-stayed bridges, this thesis issues the orientation and researching content on bridges of this kind.Besides the characters on normal cable-stayed bridges, special-shaped cable-stayed bridges take specialties as their own. Based on this, there are regular and irregular cable-stayed bridges analyzing theories which are devoted to, and method to special-shaped cable-stayed bridges is ascertained.Ascertainment of during dead load is the basis of structure analysis of cable-stayed bridges. This thesis issues some usual theories on cable force, compares principles, methods and applicable fields of each theory, and provides for further research.Analysed TEDA Street overpass, combined with previous theories, the cable forces after construction ascertained. Taking it as initial state, unitary analysis, partial stress checking and stability of tower are carries out, and computing theory is proved to be applicable and effective.Importance of checking and examination is also discussed here, and usual C&E methods are compared on applicability and validity. Proper methods are applied in the project, and the methods are proved feasible, through the inspection of cable force, tower elevation, beam elevation and stress.
